Generate tens of thousands of subdomain combinations in a matter of seconds


![mksub](mksub.png "mksub")

Read a wordlist file and generate subdomain combinations for a given domain or list of domains. Input from the wordlist file is lowercased and only unique words are processed. Additionally, wordlist can be filtered using regex.

When you use mksub's `-l` parameter, it will generate all subdomain combinations up to the specified level, including all lower levels, using words from the wordlist. For instance, with `-l 2`, it will generate `len(permutation_list)^2 + len(permutation_list)` results, which is:

- 30 combinations for a 5-word wordlist.

- 10100 combinations for a 100-word wordlist. 

- 250500 combinations for a 500-word wordlist.
